Q.
Arrange the following compounds in increasing order of their solubilities in chloroform.

$NaCl$ , ${CH}_{3} OH$ , cyclohexane, ${CH}_{3} CN$ [2024]

1 $N a C l < C H_{3} C N < C H_{3} O H <$ Cyclohexane

2 $C H_{3} O H < C H_{3} C N < N a C l <$ Cyclohexane

3 $N a C l < C H_{3} O H < C H_{3} C N <$ Cyclohexane

4 Cyclohexane $< C H_{3} C N < C H_{3} O H < N a C l$

Ans.
(3)

Since, $C H C l_{3}$ is an organic solvent, covalent (non-polar) compounds will be more soluble in it. As the dipole moment of solute increases, solubility in chloroform decreases. Due to H-bonding, $C H_{3} O H$ will be less soluble than $C H_{3} C N$ . Hence, increasing order of solubility is, $NaCl < {CH}_{3} OH < {CH}_{3} CN < cyclohexane .$
